●When driving on winding roads or roads that are uneven
●When driving on rough or unpaved roads
■When changing the tires
Depending on the tires used, sufficient performance may not be maintainable.
■Warning messages for the LDA system
Warning messages are used to indicate a syst em malfunction or to inform the driver of
the need for caution while driving. ( P. 549)
WARNING
■Before using the LDA system
Do not rely solely on the LDA system. The LDA system does not drive the vehicle auto- matically, nor does it reduce the amount of care you need to take. As such, the driver
must always assume full responsibility fo r understanding his/her surroundings, for operating the steering wheel to correct the driving line, and for driving safely.
Inappropriate or negligent driving could lead to an accident.
■To avoid operating the LDA by mistake
Switch the LDA system off using the LDA switch when not in use.
■Situations unsuitable for LDA system
Do not use the LDA system in any of the following situations.
Otherwise, the system may not function correctly and could result in an accident.
●When driving with tire chains, a spare tire, or similar equipment
●When there are objects or structures along the roadside that might be misinterpreted as lane markers (such as guardrails, a curb, reflector posts, etc.)
●When driving on snowy roads
●When pavement lane markers are difficult to see due to rain, snow, fog, sand, dirt, etc.
●When there are visible lines on the pavement from road repairs, or if the remains of old lane markers are still visible on the road
●When driving on a road with lane closures due to maintenance, or when driving in a temporary lane

NOTICE
■To prevent damage to or incorrect operation of the LDA system
●Do not modify the headlights or attach stickers to the surface of the lights.
●Do not modify the suspension.
If any suspension parts need to be replac ed, contact any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.
●Do not install or place anything on the h ood or the grille. Also, do not install a grille
guard (bull bars, kangaroo bar etc.).
●If your windshield needs repairs, contact any authorized Lexus dealer or repairer, or another duly qualified an d equipped professional.
■Camera sensor
Observe the following to ensure that the LDA system functions correctly.
●Keep the windshield clean at all times.
Performance could be affected if the windshie ld is dirty, or if raindrops, condensation or ice are adhering to the windshield.
●Do not spill liquid onto the camera sensor.
●Do not attach window tinting to the windshield.
●Do not install an antenna in front of the camera lens.
●If the area of the windshield in front of the camera sensor is fogged up, use the wind-
shield defogger to remove the fog. When it is cold, setting the heater to blow air to the feet only may cause the area ofthe windshield in front of the camera sensor to fog up. This will have a negative effect
on the images.
●Do not scratch the camera lens, or let it get dirty. When cleaning the inside of the windshield, be careful not to get any glass cleaner
etc. on the lens. Also, do not touch the lens. For lens repair, contact any authorized Lexus dealer or repairer, or another duly qual- ified and equipped professional.
●Do not change the installation position or direction of the camera sensor or remove it. The direction of the camera sensor is precisely adjusted.
●Do not subject the camera sensor to strong impact or force, and do not disassemble
the camera sensor.
●If the windshield needs to be replaced, contact any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.
●Do not attach a sticker or other items to thewindshield near the camera sensor.

RC300h_EE(OM24740E)
■Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may also be occa- sions when the sensor cannot detect pedestrians, animals, bicycles, motorcycles, trees,
or snowdrifts.
■Situations in which the pre-crash safe ty system does not function properly
The system may not function effectively in situations such as the following:
●On roads with sharp bends or uneven surfaces
●If a vehicle suddenly moves in front of your vehicle, such as at an intersection
●If a vehicle suddenly cuts in front of your vehicle, such as when overtaking
●In inclement weather such as heavy rain, fog, snow or sand storms
●If the vehicle is skidding when VSC is not operating
●When your vehicle is steeply inclined
●When only part of your vehicle’s front end collides with, or contacts, a vehicle or object in a frontal collision
●When the radar sensor moves off position due to its surrounding area being subjected
to a strong impact
●When an obstacle suddenly appears in front of the vehicle due to the steering wheel being turned sharply or another cause
■Automatic cancelation of the pre-crash safety system
When a malfunction occurs due to sensor contamination, etc. that results in the sensors being unable to detect obstacles, the pre-crash safety system will be automatically dis-
abled. In this case, the system will not activ ate even if there is a collision possibility.
■When there is a malfunction in the system or if the system is temporarily unusable
The pre-crash safety system warning light will flash and warning messages will be dis- played. ( P. 538, 549)
